Inviting collaborators to a personal repository

If you're using GitHub Free, you can add unlimited collaborators on public repositories, and up to three collaborators on private repositories owned by your personal account. To add more than three other people as repository collaborators, upgrade to GitHub Pro. For more information, see "GitHub's products."

You can invite users to become collaborators to your personal repository.

Note: GitHub limits the number of people who can be invited to a repository within a 24-hour period. If you exceed this limit, either wait 24 hours or create an organization to collaborate with more people.

Ask for the username of the person you're inviting as a collaborator. If they don't have a username yet, they can sign up for GitHub For more information, see "Signing up for a new GitHub account".

On GitHub, navigate to the main page of the repository.

Under your repository name, click Settings.

In the left sidebar, click Collaborators.

Under "Collaborators", start typing the collaborator's username.

Select the collaborator's username from the drop-down menu.

Click Add collaborator.

The user will receive an email inviting them to the repository. Once they accept your invitation, they will have collaborator access to your repository.
